Best Solar Generator For Preppers Review
How to Choose the Right Solar Generator
Choosing the right solar generator involves understanding your power needs and the features that best address them. Here’s a breakdown to guide your decision.
Capacity (Wh) – How Much Power Do You Need?
The capacity, measured in Watt-hours (Wh), is the most crucial factor. This determines how long the generator can power your devices. To calculate your needs, list the appliances you intend to run and their wattage. Multiply the wattage by the hours you’ll use each appliance daily. Sum these figures to get your total daily Wh requirement.
- Low Usage (Phones, lights, small radios): 100-300Wh might suffice for weekend camping.
- Moderate Usage (Laptop, CPAP, small fridge): 500-1000Wh is a good starting point for longer trips or basic home backup.
- High Usage (Power tools, larger appliances): 1000Wh+ is necessary for extended off-grid living or powering essential home appliances during outages. Don’t underestimate, it is better to have extra capacity than run out of power.
Output (Watts) – Can It Run Your Devices?
Output, measured in Watts (W), dictates which appliances the generator can start and run simultaneously. Some devices, like refrigerators and power tools, require a surge of power when starting up (surge wattage is higher than running wattage).
- Low-Wattage Devices (Phones, laptops): 300-600W output is typically sufficient.
- Moderate-Wattage Devices (Small appliances, power tools): 600-1800W output is ideal.
- High-Wattage Devices (Air conditioners, large refrigerators): 1800W+ output is essential.
Ensure the generator’s continuous output exceeds the running wattage of your devices and its surge wattage handles the startup demands.
Battery Type & Lifespan
The battery type significantly impacts the generator’s lifespan and performance.
- Lithium-ion: Lighter and more energy-dense but typically have a shorter lifespan (around 500-1000 cycles).
- LiFePO4 (Lithium Iron Phosphate): More expensive initially but offers exceptional longevity (3000+ cycles) and improved safety. LiFePO4 batteries are becoming increasingly common in higher-end solar generators due to their durability.
Consider the number of charge/discharge cycles the battery is rated for. A higher number indicates a longer lifespan.
Charging Options & Speed
Consider how you’ll recharge the generator.
- AC Wall Outlet: Fastest charging method, but requires access to a power source.
- Solar Panels: Environmentally friendly and ideal for off-grid use. Charging speed depends on panel wattage and sunlight conditions.
- Car Charger: Convenient for on-the-go charging.
- USB-C: increasingly common for fast charging and flexibility.
Faster charging speeds are valuable, especially during emergencies. Look for generators with high input wattage capabilities for faster recharge times with AC or solar input.

FAQs
What size solar generator do I need for prepping?
The ideal size depends on your essential power needs. For basic needs like lights and charging devices, 500-1000Wh is a good start. For running larger appliances like refrigerators or power tools, you’ll need 1000Wh or more. Prioritize calculating your total daily Watt-hour (Wh) requirement to ensure adequate capacity.
What is the difference between LiFePO4 and Lithium-ion batteries in a solar generator?
LiFePO4 batteries offer a significantly longer lifespan (3000+ cycles) and are generally safer than traditional Lithium-ion batteries (around 500-1000 cycles). While LiFePO4 batteries are typically more expensive upfront, their longevity makes them a cost-effective choice for long-term preparedness.
How important is surge wattage when choosing a solar generator?
Surge wattage is crucial if you need to power devices that require a burst of energy when starting up, such as refrigerators, freezers, or power tools. Ensure your generator’s surge wattage capacity exceeds the starting wattage of these appliances to avoid overloading the system.
How quickly can I recharge a solar generator with solar panels?
Recharge time depends on the wattage of your solar panels and the amount of sunlight. A higher wattage panel and direct sunlight will result in faster charging. Look for generators with high input wattage capabilities to maximize solar recharging speed.
